Mathematical Freshness Score for Seafood

Researchers developed a single mathematical model that predicts the lab‑measured K‑value (a biochemical freshness metric) across multiple fish species using storage time and temperature, removing the need for routine sampling. The model closely matched laboratory measurements in tests and could be used to estimate freshness continuously along long shipping routes. — If adopted by buyers, regulators, or platforms, the score could shift how seafood is certified, reduce waste, alter trade disputes about spoilage, and change the economics of cold‑chain investments.
